Dynamic financial analysis (DFA) is method for assessing the risks of an insurance company using a holistic model as opposed to traditional actuarial analysis, which analyzes risks individually. Specifically, DFA reveals the dependencies of hazards and their impacts on the insurance company's financial well being as a whole such as business mix ...
De Moivre's Law is a survival model applied in actuarial science, named for Abraham de Moivre. [ 1 ] [ 2 ] [ 3 ] It is a simple law of mortality based on a linear survival function . Definition
Survival models can be viewed as consisting of two parts: the underlying baseline hazard function, often denoted (), describing how the risk of event per time unit changes over time at baseline levels of covariates; and the effect parameters, describing how the hazard varies in response to explanatory covariates. A typical medical example would ...
Survival analysis is a branch of statistics for analyzing the expected duration of time until one event occurs, such as death in biological organisms and failure in mechanical systems. This topic is called reliability theory , reliability analysis or reliability engineering in engineering , duration analysis or duration modelling in economics ...
The GEV distribution is widely used in the treatment of "tail risks" in fields ranging from insurance to finance. In the latter case, it has been considered as a means of assessing various financial risks via metrics such as value at risk. [7] [8] Fitted GEV probability distribution to monthly maximum one-day rainfalls in October, Surinam [9]
Some state departments of insurance allow insurers to use cat modeling in their rate filings to help determine how much premium their policyholders are charged in catastrophe-prone areas. Insurance rating agencies such as A. M. Best and Standard & Poor's use cat modeling to assess the financial strength of insurers that take on catastrophe risk.
The owners of London's ExCel conference centre on Friday won an appeal brought by insurers, including Allianz, over pandemic-related losses, which its lawyers said could help thousands of other ...
The computations of life insurance premiums and reserving requirements are rather complex, and actuaries developed techniques to make the calculations as easy as possible, for example "commutation functions" (essentially precalculated columns of summations over time of discounted values of survival and death probabilities).
